Actinia

Description

"A genus of marine animals closely allied to the Hydraform Polypi, but of much greater size, and always living separately, very generally affixed by the base of rocks or shells. The olk genus Actinia has been subdivided into a number of genera, and is now the type of a gamily, Actiniadae. They consist of a fleshy sac with one orifice, around which are numerous tentacula, and when these are expanded, much resemble flowers, and have therefore been called Animal Flowers and Sea Anemones." — Chambers' Encyclopedia, 1875
